I kind of followed the general directions provided by See Kate Sew blog here. This pattern provides a pocket on the inside to add additional filter material if desired. I added a pipe cleaner across the top for a nose piece in the masks I made.
And then I modified it to make a couple of smaller masks for my grandsons. I used elastic instead of ties because I thought it would be easier for them to put on and take off.
Are you making masks? What's your favorite pattern? Please share any tips you might have!
